A second round of budget talks ended this afternoon without legislative Republicans and Corbett administration negotiators reaching agreement on a bottom-line spending number for the fiscal year that starts July 1.

Testy Republican bosses stuck to a contention, voiced during this morning's round of talks, that the logistics of moving a general fund budget bill and at least a dozen pieces of enabling legislation through the House and Senate will require that an agreement be reached within the next 24 hours.

Once again, if you're tuning in late, back in February, Gov. Tom Corbett rolled out a $27.14 billion budget for fiscal 2012-13. This spring, the Senate amended the budget plan to spend $27.65 billion. Last week, Corbett made a counter offer that was believed to have come in around $27.4 billion. But no one's talking officially.

"We're continuing to grind through through issues of legislation," a visibly frustrated Senate President Pro Tempore Joe Scarnati, R-Jefferson, said as he left the meeting in Gov. Tom Corbett's executive suite. "We're working to get to a spending number."

"If we don't have one [a spending number] in the next 24 hours, the prospects of getting a budget done by June 30 start to fade," Scarnati continued.

Getting a general fund bill done, along with the enabling legislation that includes the Education Code, Welfare Code, Fiscal Code and other bills "requires days of work by staff," Scarnati said.

Using not quite the same language, House Appropriations Committee Chairman Bill Adolph, R-Delaware, confirmed Scarnati's diagnosis.

Corbett didn't attend the meeting, which got underway shortly after 3 p.m. and wrapped up around 5:15 p.m. He had "other commitments," administration spokesman Kevin Harley said. At one point, Corbett could be seen peeking out the door of his main office down the hall from the negotiating room.
